  • 100% Wet-Flow Tested To Assure It Arrives Ready To Run
  • Gold Dichromate Finish For Corrosion Resistance w/Classic Look
  • The 0-4412C is easily the winningest two barrel carburetor on the market; used for decades in circle track racing around the world. This new 500cfm 0-4412CT carburetor shares the hugely successful features of the original; but with changes aimed directly at circle track cars. The choke assembly has been removed for unobstructed airflow; plus it has been specially calibrated for circle track racing use. It comes out of the box ready to run with less modifying and less tuning at the track!
